Description
Technical field:
The present invention relates to the technical field of Treatment of Sludge, be specifically related to the charging gear of a kind of sludge drying.
Background technology:
Along with improving constantly of people's quality of life, the requirement of municipal sewage treatment also improves accordingly, and the load of municipal treatment plants increases increasingly.The sludge volume that sewage treatment plant produces accounts for and processes about the 0.3%～0.5% of water yield volume, and a large-scale wastewater treatment plant will produce the mud of even a few kiloton of hundreds of every day.According to statistics, annual mud (moisture content 80%) total output in the whole nation will quickly break through 30,000,000 tons.The features such as strong contaminative, big quantum of output, high-moisture percentage make sludge treatment problem become very thorny.Based on double attribute pollutant and the resource of mud self, recycling sludge utilizes technology mainly to include recovery energy, Land_use change, building materials utilization etc., and these utilize the premise that technology is applied to be all sludge drying.Sludge dehydrating and drying also becomes a bottlenecks increasingly highlighted, and how to realize sludge drying also becomes a key issue realizing recycling sludge utilization low-carbon (LC) therewith.
Drying sludge is the process of a Net Energy expenditure, and energy charge is used in the ratio accounting for operating cost in a standard drying system more than 80%.Therefore Treatment of Sludge belongs to highly energy-consuming trade, and the energy is the important substance basis of national economy, and it directly influences national security, sustainable development and social stability.Reducing energy consumption, enhanced heat exchange in sludge handling process, put forward high-octane utilization rate and had become as subject matter, both alleviated country's financial burden to Treatment of Sludge, again the recycling of energy in mud has been had positive impetus, development prospect is wide.
Fume waste heat is the one of boiler exhaust gas loss, the existence of flue gas loss, not only leverage the boiler effective rate of utilization to fuel, and it is discharged into the flue gas in air and also seriously compromises air quality, environment is caused very big pollution, therefore, recycles fume afterheat, while meeting energy-saving and emission-reduction themes of the times, also the recycling economy for power plant provides a practical way.
In existing sludge drying charging gear, the moisture content of wet mud is high, after wet mud feed is entered desiccation apparatus, owing to wet mud itself is containing more moisture, cause that mud drying time length and mummification efficiency in mummification mummification case reduce, and mud is once all fed in desiccation apparatus by current charging gear, cause the mud over loading in mummification case, also reduce mummification efficiency, therefore invent and a kind of just mud carried out when mud feed preheating and preliminary mummification and the charging gear of feed progress can be regulated extremely is necessary.
Summary of the invention:
The purpose of the present invention aims to solve the problem that prior art Problems existing, it is provided that a kind of can mud being carried out when mud feed preheats and preliminary mummification, and the charging gear of the sludge drying of energy conditioning of mud feed progress.
